<p>PROBLEM TO BE SOLVED: To provide a refrigerator having enhanced thermal insulating properties of a ceiling surface without causing relatively expensive feeling and concerns about quality.SOLUTION: A first vacuum heat insulation material 33 is fitted to an inner case upper surface of a portion opposing to a refrigerator control section 23 of a ceiling surface 22 that includes the refrigerator control section 23 on the rear side and an interior floodlight 24 on the front side, and a second vacuum heat insulation material 34 that is a body different from the first vacuum heat insulation material is fitted to an outer case inner surface of a portion opposing to the interior floodlight 24 of the ceiling surface. Thus, since it is unnecessary to mold the first and second vacuum heat insulation materials in accordance with the shape of the ceiling surface, e.g. an approximately Z-shape, the plate-like vacuum heat insulation materials can be used without change, and the versatile vacuum heat insulation materials solidified by using a binder can be used. This can drastically reduce the possibility that the vacuum heat insulation materials may be deformed to cause a core material to damage a casing material for gas barrier during transportation, etc. in a production process and can improve thermal insulating properties of the ceiling surface without causing relatively expensive feeling and concerns about quality.</p> |
